Afghan Dam Constructions Threaten Iran Water Share

Construction of the Kamal Khan Dam on Helmand River now near completion will profoundly affect water supply to Iranian wetlands and aggravate environmental problems in east and southeastern Iran, Iran's former ambassador to Afghanistan said.
“The government in Kabul has completed the second phase of Kajaki Dam, the largest of its kind in Afghanistan. It is planning to build Bakshabad Dam on Farah River, another joint basin,” Abolfazl Zohrevand was quoted as saying by ILNA.
After completion, Kamal Khan Dam will divert large quantities of water into Afghan farmlands (mostly to plant poppies) instead of the river delta’s wetlands where Helmand ends.
Prior to construction of the dams on Helmand River, nine billion cubic meters of water flowed annually into Hamoun Wetlands in Iran’s Sistan-Baluchestan Province. That has now declined to less than 800 mcm per annum, he said.
